2015-03-09sPAPR: Implement EEH RTAS callsGavin Shan
The emulation for EEH RTAS requests from guest isn't covered by QEMU yet and the patch implements them. The patch defines constants used by EEH RTAS calls and adds callbacks sPAPRPHBClass::{eeh_set_option, eeh_get_state, eeh_reset, eeh_configure}, which are going to be used as follows: * RTAS calls are received in spapr_pci.c, sanity check is done there. * RTAS handlers handle what they can. If there is something it cannot handle and the corresponding sPAPRPHBClass callback is defined, it is called. * Those callbacks are only implemented for VFIO now. They do ioctl() to the IOMMU container fd to complete the calls. Error codes from that ioctl() are transferred back to the guest.

2015-03-09target-ppc: Add versions to server CPU descriptionsAlexey Kardashevskiy
5b79b1c "target-ppc: Create versionless CPU class per family if KVM" added a dynamic CPU class registration with the name of the CPU family which QEMU is running on. For example, this allowed specifying "-cpu POWER7" on every version of POWER7 machine, not just the one which POWER7 was an alias of. I.e. before 5b79b1c, "-cpu POWER7" would not work on real POWER7 2.1 and would work on POWER7 2.3 only. The same story for POWER8. However that patch broke POWER5+ support as POWER5+ CPU uses the same name as the CPU class so dynamic registering of the POWER5+ class failed. This redefines POWER5+ server CPUs by adding a version to them and adding an alias for TCG case. KVM will use dynamically registered CPUs. While we are here, do the same for 970 CPU.

2015-03-09PPC: Introduce the Virtual Time Base (VTB) SPR registerCyril Bur
This patch adds basic support for the VTB. PowerISA: The Virtual Time Base (VTB) is a 64-bit incrementing counter. Virtual Time Base increments at the same rate as the Time Base until its value becomes 0xFFFF_FFFF_FFFF_FFFF (2 64 - 1); at the next increment its value becomes 0x0000_0000_0000_0000. There is no interrupt or other indication when this occurs. The operation of the Virtual Time Base has the following additional properties. 1. Loading a GPR from the Virtual Time Base has no effect on the accuracy of the Virtual Time Base. 2. Copying the contents of a GPR to the Virtual Time Base replaces the contents of the Virtual Time Base with the contents of the GPR.

2015-03-09pseries: Switch VGA endian on H_SET_MODEDavid Gibson

2015-03-09vga: Expose framebuffer byteorder as a QOM propertyDavid Gibson
The VGA device model now supports having the framebuffer in either endian, and can be switched between these by the guest via a register in the qext region. However, in some cases (e.g. LE OS on the pseries machine) we have existing guest that don't know about the endian switch register, but other parts of the qemu code have better information to set a default endianness than the VGA code does of itself. In order to allow them to set a correct default endianness in these cases, without breaking abstraction walls, this patch exposes the VGA framebuffer endianness via a writable QOM property.

2015-03-09spapr: Clean up misuse of qdev_init() in xics-kvm creationMarkus Armbruster
We call try_create_xics() to create a "xics-kvm". If it fails, we call it again to fall back to plain "xics". try_create_xics() uses qdev_init(). qdev_init()'s error handling has an unwanted side effect: it calls qerror_report_err(), which prints to stderr. Looks like an error, but isn't. In QMP context, it would stash the error in the monitor instead, making the QMP command fail. Fortunately, it's only called from board initialization, never in QMP context. Clean up by cutting out the qdev_init() middle-man: set property "realized" directly. While there, improve the error message when we can't satisfy an explicit user request for "xics-kvm", and exit(1) instead of abort(). Simplify the abort when we can't create "xics".

2015-03-09pseries: Export RTC time via QOMDavid Gibson
On x86, the guest's RTC can be read with QMP, either from the RTC device's "date" property or via the "rtc-time" property on the machine (which is an alias to the former). This is set up in the mc146818rtc driver, and doesn't work on other targets. This patch adds a similar "date" property to the pseries machine's RTAS RTC and adds a compatible alias to the machine.

2015-03-09pseries: Move rtc_offset into RTC device's state structureDavid Gibson
The initial creation of the PAPR RTC qdev class left a wart - the rtc's offset was left in the sPAPREnvironment structure, accessed via a global. This patch moves it into the RTC device's own state structure, were it belongs. This requires a small change to the migration stream format. In order to handle incoming streams from older versions, we also need to retain the rtc_offset field in the sPAPREnvironment structure, so that it can be loaded into via the vmsd, then pushed into the RTC device. Since we're changing the migration format, this also takes the opportunity to: * Change the rtc offset from a value in seconds to a value in nanoseconds, allowing nanosecond offsets between host and guest rtc time, if desired. * Remove both the already unused "next_irq" field and now unused "rtc_offset" field from the new version of the spapr migration stream Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Signed-off-by: Alexander Graf <agraf@suse.de>
2015-03-09pseries: Make the PAPR RTC a qdev deviceDavid Gibson
At present the PAPR RTC isn't a "device" as such - it's accessed only via firmware/hypervisor calls, and is handled in the sPAPR core code. This becomes inconvenient as we extend it in various ways. This patch makes the PAPR RTC a separate device in the qemu device model. For now, the only piece of device state - the rtc_offset - is still kept in the global sPAPREnvironment structure. That's clearly wrong, but leaving it to be fixed in a following patch makes for a clearer separation between the internal re-organization of the device, and the behavioural changes (because the migration stream format needs to change slightly when the offset is moved into the device's own state).

2015-03-09pseries: Make RTAS time of day functions respect -rtc optionsDavid Gibson
In the 'pseries' machine the real time clock is provided by a paravirtualized firmware interface rather than a device per se; the RTAS get-time-of-day and set-time-of-day calls. Out current implementations of those work directly off host time (with an offset), not respecting options such as clock=vm which can be specified in the -rtc command line option. This patch reworks the RTAS RTC code to respect those options, primarily by basing them on the qemu_clock_get_ns(rtc_clock) function instead of directly on qemu_get_timedate() (which essentially handles host time, not virtual rtc time). As a bonus, this means our get-time-of-day function now also returns nanoseconds. Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Signed-off-by: Alexander Graf <agraf@suse.de>
2015-03-09pseries: Add spapr_rtc_read() helper functionDavid Gibson
The virtual RTC time is used in two places in the pseries machine. First is in the RTAS get-time-of-day function which returns the RTC time to the guest. Second is in the spapr events code which is used to timestamp event messages from the hypervisor to the guest. Currently both call qemu_get_timedate() directly, but we want to change that so we can properly handle the various -rtc options. In preparation, create a helper function to return the virtual RTC time. Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Signed-off-by: Alexander Graf <agraf@suse.de>
2015-03-09pseries: Add more parameter validation in RTAS time of day functionsDavid Gibson
